Struct SpringTimeStep 

pub struct SpringTimeStep<F> { /* private fields */ }

Cached coefficients for a spring, based on its configuration and a particular time step.

Used to efficiently update one or more springs that share the same configuration.

Usage

To derive a SpringTimeStep, you must first get a SpringParams from a SpringConfig:

// configure your spring...
let config = SpringConfig::new(5.0, 0.75);
let mut spring = Spring::new();

// derive its state
let state = SpringParams::from(config);

// then, either create your own `SpringTimeStep`...
let time_step = SpringTimeStep::new(state, delta_time);
spring.update(time_step);

// or let `Spring::update_single` do it for you
spring.update_single(state, delta_time);

Implementations

impl<F: Float> SpringTimeStep<F>

pub fn new(state: impl Into<SpringParams<F>>, delta: F) -> Self

Derive a spring time step from a particular delta time.

pub fn update_many(self, springs: &mut [&mut Spring<F>])

Update multiple springs using this time step. Simply calls Spring::update on each passed spring.

Trait Implementations

impl<F: Clone> Clone for SpringTimeStep<F>

fn clone(&self) -> SpringTimeStep<F>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<F: Debug> Debug for SpringTimeStep<F>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<F: Float> Default for SpringTimeStep<F>

fn default() -> Self

Returns the “default value” for a type.

impl<F: PartialEq> PartialEq for SpringTimeStep<F>

fn eq(&self, other: &SpringTimeStep<F>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
